Using clean coal technologies is important to reduce environmental damage as coal of lower quality has high sulphur content. One form of well developed technology in this respect is flue gas scrubbing to remove sulphur dioxide and nitric oxide. [1]

The Government has yet to speed up the Flue Desulphurisation Gas facility at Castle Peak and to negotiate a moratorium on the use of sulphur rich fuels in power generation on both sides of the boundary. Clear long term policy in power generation, such as on whether the use of coal will be permitted, and under what circumstances in terms of sulphur and ash content and emission controls should be developed. [2]

The Hong Kong and Guangdong Governments introduced an Emissions Trading Scheme (plants are allocated emissions allowances and can purchase credits from other plants to cover its actual emissions quantities) in 2007 but no trades have been attempted yet.[3]
